I don't think it is getting off topic to speculate about whether or not intelligent design might have been tied in with extra terrestrial encounters. One has to wonder, when it is estimated that other planets capable of life could have pre-dated earth by millions of years, about seedings and interventions and such. Our entire galaxy is but a grain of sand in the entire Universe and we are but a grain of sand in our galaxy. It is a BIG universe! To think that it was all created centered around our little speck seems absurd to the Nth degree. Which does not preclude a Creator at all, it merely takes it out of the tiny box some would put it in.
